To all whom it may concern.-

Be it known that 1, ANDREW I. HANSEN, of London, England, have invented certain new and useful Improvements in Type-Writ ing Machines, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Fig. 4, Sheet 2, is aside elevation of a modified form of the improvement. Fig. 5, Sheet 2, is an elevation of the indicator and key. Fig. 6, Sheet 2, is a rear elevation of the letter-spacing slide. Fig. 7, Sheet 2, is a side elevation of another modified form of the improvement. Fig. 8, Sheet 3, is a plan view of a modified form of the improvement. Fig. 9, Sheet 3, is a side elevation of the same. Fig. 10, Sheet 3, is a side elevation of the type-bar. Fig. 11, Sheet 3, is a sectional elevation of one of the modified forms of my invention, said section being taken through the line 3 y, Fig. 8.

My invention relates to improvements in type-writing machines wherein .the printing of letters and other symbols is effected by the action of the hand; and it consists of the several combinations and arrangements of parts,

, substantially as hereinafter fully set forth.

According to one mode of carrying my in-' vention into effect,I employ, according to Figs. 1, 2, and 3 of the accompanying drawings, a base-plate or table, A, and mount thereon brackets a, supporting a horizontal shaft, B. Upon such shaft I place a sliding frame, 0, capable of being freely moved thereon. Upon such slide 0, I mount a tablet supported by two screw-pivots, b, in such a manner as to swing freely thereon. This tablet or lever D is provided with an index formed thereon in any suitable manner, representing the various characters necessary for writing, and these are formed upon it at regular or irregular inter vals on one or more of its sides or its surface;

Upon slide C is mounted a spring, WV, tending to keep the lever in a normal position above the table A, upon which the paper to be printed upon is secured. \Vithin a groove in this tablet or lever Dis placed abar or rack, E, carrying the types, which are formed upon it or connected therewith in any suitable manner and at distances from each other made to correspond with the index on the lever D. This type-rack E, which represents one form of the type mechanism, can be freely moved back and forward in the groove cl of lever D, by means of an index-key, k, and indicator f, for'the purpose hereinafter explained.

On one or both sides of the index-lever D are mounted racks 9, provided with recesses corresponding in shape with the indicator f, their number and distance from each other corresponding with the number and distance apart of the characters on the index-lever D.

A spring, 6, is attached to the type-rack E and secured to the key It and indicator f in or der to maintain the indicator in a normal position above the tooth-racks g.

Unto the index -lever I attach a pawl, O, gearing into a rack, F, secured to table Aand running parallel with shaft B. On the other end of table A, I place two corrugated feed-. rollers, m, running parallel with shaft B. One has its hearings in table A. The other is supported by movable or hinged bearings H, which are secured to table A. These rollers are'brought into contact with each other by means of a spring or springs, h, attached to such hinged bearings for the purpose of supporting the paper to be printed upon. To

one of these rollers I firmly attach a ratchetwheel, N.

O is a pawl-lever moving freely on the pivoted end of such roller, its attached pawl 12 gearing into the ratchet-wheel N. A spring, n, keeps the pawl-lever, with its attached pawl p, in a normal position.

1 A tension spring or springs, Q, tend to press or keep the paper I? to be printed upon againstaprinting-block, Z, having a convexed upper side, and which is made of an elastic material, and is secured to the table A, and whereupon the paper P is placed in such a manner as to be partly grasped by the rollers m and partly pressed down by the springQ, in order that its surface may assume the same shape as that of the convexed printing-block Z on which it rests or over which it is to be drawn.

The action of this machine is as follows: The finger of the writer is placed upon the key, and such key k is moved into such a position as will bring its attached indicator f just above the letter or sign on the index about to be printed. The rack Ewill simultaneously slide in the index-lever D and bring the corresponding type into the proper position above the convexed printing block Z. Upon then depressing the key It its attached'indicator f will fall into rack g, and thus form a lock or stop upon the index-lever D, which, by continuing the pressure upon key k, will also be depressed until the type rack E touches the paper placed on the convexed printing-block Z, and thus the letter or sign indicated by the key k and indicator f is transferred to the paper I by means of the interposition of an ink ribbon or any other suitable inking appliance. Simultaneously with theindex-lever being depressed its attached pawl 0' will gear into the rack F, and thus force the sliding frame 0 and its attached index -lever D the distance of one or more teeth, which represents the space between letter and letter. On releasing the pressure on key It and indexlever D both will resume their normal position, and pawl G will also free itself from the rack F on the table A. The opening between word and word is effected by means of so placing the type-rack E as will obviate its touching the paper in the act of theindex-lever being depressed. When the sliding frame 0 and its attached index-lever D have traveled to the end of bar B, they are moved back toward the opposite end, and upon the index-lever D being depressed while in this position it will simultaneously dep ress the pawllever O, which will cause its attached pawl to move the ratchet-wheel N for one or more teeth, as may be required, and thereby cause the rollers m to revolve accordingly, which will carry the paper P for a sufficient distance to form the required space between line and line. Each depression of the pawl-lever O, by or independently of the index-lever D, will cause the rollers m to revolve accordingly, and thus form the space between line and line upon the paper I? to be printed upon.

Figs. 4 and 5 show an arrangement of a segmental type mechanism in lieu of the longitudinal type-rack E. In this case I dispense with the convexed printing-block Z. The latter form of type mechanism consists of a segmental rack, S, whereunto the types are fixed in a similar manner as above referred to. The distance from type to type again corresponds with the index on the index-lever D. This segmental rack S turns freely on a pivot, 3, supported by suitable bearings attached to lever D. To the segmental rack S, I secure a A slotted arm or arms, S, which can be easily moved back and forward by means of key It and indicator f which is designed to fit,accordingly, in the slot or slots of the arm or arms S, and upon such indicator f being placed into a recess of the rack g or index on index-lever D, which represents a letter or sign, the corresponding type is simultaneously placed in the proper position above the flat or otherwise conveniently-shaped printingsurface. The impression upon the paper is caused in the same manner as above described. The spacing between word and word in this case is effected by the depression of the pawl O and pawllever 0 (shown in Fig. 6) by means of suitable key, K, such pawl-lever (3 being attached to the sliding frame 0. Each depression upon the pawl -lever C will cause the sliding frame 0 and index-lever D to travel the distance of one or more teeth, representing the space between letter and letter, without the index-lever D being depressed; but this is only applied for formingthe space between w nd Word, the spacing between letter and letter being produced by the depression of the index-lever D, which, although not attached to the pawl-lever, will rest by key K upon such pawl-lever O ,and secure its proper action in the act of the index-lever being depressed, as in Fig. 7, which also shows a modified arrangement of movable wheel, segment, and type-wheel, which I sometimes employ, instead of the sliding type-rack E or movable type-segment S, and in this case I employ a series of indicating-keys, is, within the index-lever, acting in the manner hereinafter explained. When a key which represents a sign or letter is depressed, such key will depress the wheel-segment E and thus bring the type-wheel G in the proper position, and bring the corresponding type opposite the printing block or surface, and upon such key touching the index-lever D such index-lever 'D, together with the type-wheel G, will be' depressed, and thus form the required impression. The wheelsegment E is connected to the index-lever D and supported by a spring, X, attached to index-lever D, and keeping such segment and the several pivot-keys representing letters and signs in a normal position. Thus it will be seen that the moment the pressure on any key is released the segment E, the key or keys the type-wheel G, and the index-lever will all simultaneously resume their normal position by action of springs W and X.

The same effect of printing letters, signs, or words is likewise produced by causing the index-lever D to remain stationary on the table A, and effect the moving of the paper from letter to letter, the paper being attached to a sliding frame, the mechanism to effect such moving being identically the same as the one described for moving the slide upon which the index-lever is mounted.

Instead of using a wheel, segment, and typewheel in connection with loose pivot-keys IIO contained in the index-lever D, it can also be arranged to let these keys operate on a typesegment of the same or similar form as the wheel-segment E or S.

Finally, I will state that in lieu of the'indexlever being made to oscillate,and the impression of the type upon the paper being caused by the depression of such lever, the index-lever may be non-oscillating, and the type-rack E moved in the groove (1 of tablet D in such a manner as to pass over a pin or pivot, r, fitting in a long longitudinal slot, d, formed in the rack E, in order that such rack E may act as the lever itself, as shown in Figs. 8, 9, 10, and 11 of the drawings. In this case the indicating-key his affixed rigidly to the rack E.

The spacing between letter and letter is caused by the depression of the type-rack E upon the pawl-lever 0 simultaneously with the impression being made upon block Z. In order to support the index-tablet sufliciently, an additional bar, B, is mounted on the other end of the table, and the index-tablet traverses upon such bars.

A spring, 0, is attached to the indicator f, keeping the said indicator above the racks g, and also keeping the type-rack E above the pawl-lever (J and printing-block.

It will be seen that the index-tablet D itself forms the slide.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent- 1. In a type-writing machine, the index or character bar or device, adapted to travel across the table to space apart the letters or words, in combinationwith the type-carrier rack, adapted to operate substantially as described with relation to the movement of the index or character device and to produce the impression upon the paper or surface to be printed upon, substantially as and for the purpose set forth.

2. In a type-writing machine, the index or character bar or device, adapted to travel across the table to space apart the letters, in combination with and adapted to actuate the mechanism for moving the paper or surface being printed upon, substantially as and for the purpose set forth.

3. In a type-writing machine, the combination of the index or character bar or device adapted to travel across the table, the typecarrier rack arranged to operate substantially as described with relation to the movement of 4. In a type-writing machine, the combination, with the longitudinally-slotted index bar or lever having the racks 99, of the type carrier rack E, adapted to move in the slot of 6 5 said bar or lever and having the indicator f, having a finger-piece and an elevating-spring, substantially as and for the purpose set forth.

5. In a type-writing machine, the combination, with the table A, having the transversely-arranged rack F, and bar B disposed parallel with the said rack, of the lever D and its carrying-frame C, said lever being provided with the pawl 0, spring W, acting upon the lever D, and the sliding type-carrier rack E, having a spring key or finger piece, k e, pro vided with an indicator, f, adapted to engage racks g of the lever D, substantially as and for the purpose set forth.

6. In a type-writer, the combination with the feed-rollers m and the oscillating lever D, provided with a type-carrier, of the ratchetwheel N, the pawl 19, and the pawl-lever O, substantially as herein shown and described, whereby the downward movement of the lever D to print the first character of a line will move the paper forward the space of one line, as set forth.

7. In a type-writer, the combination, with the table A, of the feed-rollers m, the pad Z, and the holding-spring Q, substantially as herein shown and described, whereby the paper is brought into and held in proper position to be printed upon, as set forth.
